�DqRў��K��q���{|c���. Technically rigorous and largely self-contained, it provides an introduction to the use of optimal control theory for deterministic continuous-time systems in economics. A Optimal Control Problem can accept constraint on the values of the control variable, for example one which constrains u(t) to be within a closed and compact set. It's a way of solving an optimization problem in continuous time. 9 0 obj %%EOF

Although control theory has deep connections with classical areas of mathematics, such as the calculus of variations and the theory of differential equations, it did not become a field in its own right until the late 1950s and early 1960s. 0000004243 00000 n

Initially, optimal control theory foundits application mainly in engi-neering disciplines like aeronautics, chemical and electrical engineering, robotics. These turn out to be sometimes subtle problems, as the following collection of examples illustrates. Agrachev A.A., Sachkov Y.L. 0000004640 00000 n
